Welcome

The Arizona Trail Association’s Endurance Events take place on premier segments of the Arizona National Scenic Trail. Please explore the site and find out more about our trail running and mountain biking events, which directly benefit the maintenance and protection of the AZT. Due to COVID-19 we canceled most events in 2020 and 2021. We look forward to bringing these fun and popular gatherings back as soon as it’s safe to do so — hopefully later in 2021. The dates listed below are only tentative, and more information will be provided soon.

The Oracle Rumble takes place near the beautiful, historic town of Oracle, Arizona, located just north of Tucson on the north side of the mighty Santa Catalina Mountains. The event is mostly singletrack through Oracle State Park (OSP) and follows magnificent and remote sections of the Arizona Trail (AZT) in Pinal County. The course is constantly rolling, making this a very challenging event for all distances. Your reward is that the views are often breathtaking!
